Hi,
If you wish to find NUMBERS which are missing, i think you can try
this:
set @a:=0; /*initialise variable a*/
select @a:=@a+1,IF(YOUR_COLUMN_INT_TYPE= @a,'OK',@a:= @a+1) FROM YOUR TABLE;
Don't forget to initialise variable 'a' for every time when run the second
query.
This is work indeed but if you want to have a definitively solution i think
you should to do an UDF where you can make some rules and conditions to
checking what data is missing from the table field(column).
Hope it's help
Regards,
Gelu
